Accurate Hitboxes

Accurate Hitboxes replaces Minecraft's broad entity hit detection with hitboxes derived from visible model parts. Attacks and projectiles must intersect the model geometry instead of only the vanilla bounding box.

Features

Per-part hitboxes for vanilla and many modded entities
Animated hitboxes that follow model movement, rotation, scaling, and entity state
Dedicated-server synchronization for current rendered geometry
GeckoLib 4 support when GeckoLib is installed
Blacklist and whitelist configuration modes
Green per-part debug outlines with F3+B
TaCZ bullet compatibility on Forge/NeoForge 1.20.1
Baby and scaled-entity support

Requirements

Accurate Hitboxes must be installed on both the client and server. Connections without the required server installation use vanilla interaction behavior.

The current mod release supports Minecraft 1.20.1:

Fabric and Quilt
Forge and NeoForge

Older releases are available for Minecraft 1.20.2 and 1.20.3.

Configuration

The configuration file is located at:

config/accuratehitboxes.json

Set mode to:

blacklist to disable accurate hitboxes for listed entity IDs
whitelist to enable accurate hitboxes only for listed entity IDs

The Ender Dragon and its entity parts are excluded by default because Minecraft handles that boss through its own multipart collision system.

Compatibility Notes

GeckoLib 4 is detected automatically and remains optional.
Sodium and Iris use different rendering paths; compatibility can depend on the exact mod versions and shader setup.
With EMF/ETF custom models, collision and the green debug overlay may follow the underlying vanilla model rather than the replacement model.
Highly unusual renderers or entities that do not use supported model structures may fall back to vanilla hit detection.
